Car freaks out at Idle and has loss of power

Business Kat · 08-19-2015, 01:38 PM

My car learned a new trick! I was driving on the freeway and then some lights came on and the car kept losing power. Now the car won't go over about 1500 rpms. A guy with a g35 pulled over and informed me my car is in limp mode but I after doing research I'm not sure if that's the case. There was no reason for it to go limp. One time I went to start it and it just kept turning. But then the next attempt it started up.

At this point I don't think its mechanical, I'm pretty sure it's haunted. Is it possible to hold a seance for a car?

Are your spark plugs ok and throttle body clean? My car would not start sometimes and almost die at idle before having them both serviced.

Sounds like you have a grounding issue somewhere. If all you sensors reading are all over the place then it needs to be something shared. If the pcm logic ground is off then all sensor readings will be off too. Need to start checking your data values, reference voltages and voltage drops. You can try a seance but electrical gremlins are pretty immune to them.
